I don't recommend the 12 dollar etymotics over this which is 20. https://www.amazon.com/gp/product/B0032BYCWG/ref=s9_acsd_al_bw_c_x_4_w

So I will start with the list of things I already have saved from surfing this sub

These are great to put over your tent to keep the light and heat out in the morning so you dont wake up in a sauna at 7am
And finally, I will never attend another festival again without this stuff, it is a foaming body wash that does not require water. We use it at my work all the time for bed baths and whatnot, so I thought I would try it for a festival and it works quite well. It doesnt get you as clean as a normal shower but this and baby wipes can keep you feeling fresh the whole weekend (just dont use it on hair)

Seconding bringing a bunch of foam plugs to give away. I also use foam plugs at really loud shows.
For music plugs I use these. They’re relatively cheap and — most importantly for me — they’re a good fit for my tiny ears.

Earplugs are important, yo.
These are probably the best you can get for $15-$20, but personally I am not not happy about them - they distort bass quite noticably. I'd say 7/10.
I have the Alpine pros and I think the 20 dollar ones should do. https://www.amazon.com/gp/product/B0032BYCWG/ref=s9_acsd_al_bw_c_x_4_w
Pros have less reducing filters, and extra earplug in case you lose one.
I enjoy earaser branded ones and alpine because they don't stick out of your ear as much as the etymotics. They also sound better than the cheaper etymotics, I haven't tried the higher one ones.
